You can put this solution on YOUR website!
one solar heating panel can raise the temperature of water 1° in 16 min.
\n" ); document.write( " a second solar heating panel can raise the temperature 1° in 24 min.
\n" ); document.write( " how long will it take to raise the temperature of the water 1° if both panels are operating?
\n" ); document.write( ":
\n" ); document.write( "let b = time required when both panels are operating
\n" ); document.write( "let the completed job = 1 (raising the temp 1 degree)
\n" ); document.write( ":

\n" ); document.write( ":
\n" ); document.write( "\"b%2F16\" + \"b%2F24\" = 1
\n" ); document.write( "multiply by 48 to clear the denominators, results:
\n" ); document.write( "3b + 2b = 48
\n" ); document.write( "5b = 48
\n" ); document.write( "b = 48/5
\n" ); document.write( "b = 9.6 minutes working together
